RE: [docbook-apps] emacs nXML and DocBook V5.0CR5

Jason,

I find that "Unknown element" usually indicates a mismatch in namespace
between an XML file xmlns assignment and the RNC namespace declaration.

In your case you have accidentally replaced the "/" in the default xmlns
with a ".".

Change to xmlns="http://docbook.org/ns/docbook"; and you'll be good to go.

Jim

Subject: [docbook-apps] emacs nXML and DocBook V5.0CR5

I'm trying to use emacs with nXML and DocBook V5.0CR5. I am getting
the following behavior:

I get completion for the article tag. If I close the tag I get an
error requesting ``xmlns="http://doc...";''. If I put that in the tag,
like in the listing below, nxml says article is ``Unknown element''.
C-c C-s C-w says that I am looking at the correct rnc file.

How can I fix this? Am I using incompatible versions of tools?

Thanks, Jason

Fedora Core 7
